説明
Describe the bug Attempting to load a non-existent column from a Parquet file throws ArrayIndexOutOfBoundsException instead of a more specific error.
Steps/Code to reproduce bug Try to load a single column name that does not exist from a Parquet file. For example:
Table.readParquet(ParquetOptions.builder().includeColumn("doesnotexist").build(), new java.io.File("data.parquet"))
throws the following exception:
java.lang.ArrayIndexOutOfBoundsException: 0
at ai.rapids.cudf.Table.<init>(Table.java:96)
at ai.rapids.cudf.Table.readParquet(Table.java:974)
... 49 elided
Expected behavior A more useful error exception/message should be used than an array index error.
